    """Comprehensive test for the User.auth_method GraphQL resolver.

    Tests all authentication methods and verifies the resolver correctly:
    1. Returns LOCAL for local authentication users
    2. Returns OAUTH2 for OAuth2 users
    3. Returns LDAP for LDAP users (stored as OAUTH2 with Unicode marker)
    4. Correctly translates the database storage to semantic types

    This test uses real database records and GraphQL queries (no mocks).
